PCStats take a further look at the Corsair's latest 240 pin DDR2-800 memory, the 2GB Twin2X2048-6400C3 kit. What sets the 6400C3 kit apart from the rest are its timings... and they are some of the lowest anywhere. According to Corsair, the Twin2X2048-6400C3 memory is rated to run at DDR2-800 speeds with CAS latency timings of 3-4-3-9, albeit with a voltage of 2.2V. This memory comes with a huge price tag however, retailing for $505 CDN ($454 US, L243 GBP). Ouch!

Corsair's Twin2X2048-6400C3 memory is the first DDR2-800 class memory that can run with a CAS Latency of 3. Finally there is some true low latency memory on the market, and as everyone knows, the AMD Athlon64 loves memory that uses tight timings. From the benchmarks, you can see that the tighter timings give the system slightly better performance than the memory that's rated at 4-4-4-12.

From 3DMark05, Doom 3 and Business Winstone 2004, everything was just faster on the Corsair Twin2X2048-6400C3. To get to those timings, Corsair had to increase the default voltage from 1.8V to 2.2V, which is quite a jump but definitely well worth it.

With the tight 3-4-3-9 timings the Corsair Twin2X2048-6400C3 did not overclock very high hitting a maximum speed of 218 MHz or DDR2-872. Loosening up the timings to JEDEC DDR2-800 standard of 5-5-5-15 allowed the memory run as fast as 264 MHz while maintaining 100% stability.
